RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - atcusb - 2016-08-09
Thanks Fritsch, I saw comments around the removal of Intel EGL drivers and jumped to the wrong conclusion. I then panicked that my next apt-get exercise that I was just about to upgrade, was going to remove EGL from my beebox....
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - soder - 2016-08-10
Hi (again)! I just want to see if I got it all right now. =)
I use OpenELEC 6.0.398-Intel_EGL and hasn't updated to OpenELEC 7.x and therefore also not Kodi 16. When I asked about a EGL-version based on Kodi 16 I got the answer Kodi 17 was "the shit" and you pointed to some download server with EGL-version of Kodi 17.
Am I correct that all your nice work are built in to the main OpenELEC 8.x/Kodi 17 releases (nightlies) now? If I still want the 4K on a Braswell that's what I need to install?
Thanks.

Yes. Take care of xrandr settings.

Is that since it's moved to the main Kodi 17 build? I think that auto start feature wasn't needed after a while in your custom builds?
BTW, where do I find the OpenELEC nightly builds?
EDIT: Also, where can I find the older versions like OpenELEC 6.0.398-Intel_EGL, if I need to go back to the working version I got now.

Do your research, please. This is no support Hotline.

Of course not, but I find it very hard to find old URL's to download pages, since there's almost 300 pages.
I hope I can get some help finding these.
EDIT: I found OpenELEC-Generic.x86_64-6.0.398-Intel_EGL.img at http://kodi.wiki/view/Chromebox#OS_and_Kodi_Installation
and https://dl.dropboxusercontent.com/u/98309225/OpenELEC-Generic.x86_64-6.0.398-Intel_EGL.tar
Also, I've been away from all this kind of HTPC tech talk (since I've become a father) and during that period there is LibreELEC and I don't understand if OE is no more or not..

RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - tudstudent - 2016-08-11
Fritisch, can you explain how I should interpret this setting:
Quote:Adjust display refresh rate to match video: On Start / Stop
In my imagination this should mean that when my video is 1080i Kodi is outputting 1080i to the TV. However when I press "info" on my Samsung TV it keeps showing: 4K@60Hz.
Is there something wrong in my set-up? Or do I miss the point of this setting?
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - fritsch - 2016-08-11
1) kodi never switches down only up, so not all for you.
2) kodi only outputs progressive, our nice deinterlacers are used to accomplish that.
3) check the thread where I suggested to run kodi in 1080 cause of our inferior gui scaler.
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - tudstudent - 2016-08-11
I think I messed up 2 things:
1: Adjustment of refreshrate (which is done, checked it during watching a bluray, TV report 4K@24P (prob rounded up, because kodi says 23,9..)
2. Adjustment of resolution (Kodi runs on 4K and all content seems to be adjusted to this resolution)
Going to investigate your suggestion on 1080.

Adjust refresh rate enabled. Sync audio/video disabled since it should not be needed on this hardware. Scaling to Auto, delinterlacing set off.
Watching a [email protected] video at 1080p... and I can watch the VSyncOff number start at like -15 and over the next 30 seconds work its way down to 0, and then I'll have 1-5 dropped frames, and the number will reset to like -15 and do it all over again. And then to top it off, I'll get random 5 second periods with massive dropped frames like (70-100). I can play those segments over again and they'll be fine.
Feeling like I should've stuck with v15.... sure, I had to reboot it every couple of days, but at least it could play 720p videos without dropping a single frame!
(2016-07-04, 13:15)Sunflux Wrote: Okay, using the recommended settings... I'm mainly looking for the frequent dropped frames every 20-30 seconds...
480p23 + AAC 2.0 + Lanczos3 = no dropped frames (vsyncoff rock solid at 0.0)
(...)
720p29 + AAC 2.0 + Lanzcos3 = massive dropped frames (vsyncoff fluctuates from -12.5 to +3)
So... looks like there's only problems with 29p (actual 29p) and 59i/p regardless of audio, but 59 is handled through skipping frames fairly gracefully, but 29p gets horrible stuttering periods making it unwatchable. I even have a 0.5mbit 720p stream that causes hundreds of dropped frames a minute.
I have exactly the same problems (25p and 50i/p are unwatchable too) with kodi builds after 15.2.
The 6.0.398-Intel_EGL build is the last that plays fine.

...So there are surely sync issues in that file (and thousand others) and the actual method to sync those leads to massive video stuttering. On 6.0.398-Intel_EGL there is no noticable stuttering.

Of course I can post the complete debug log, but these are the parts where the different behavior of CDVDPlayer and CVideoPlayer are visible. Or maybe its a difference in ffmpeg.

Please link such a 25p Sample, we want to test. Preferrably Dropbox.

I found a sample: http://fritsch.fruehberger.net/samples/sample-stutter-bsw.mkv <- same issue with that one? (Edit: Be careful with the content - I don't know who posted it ... it's nothing for kids)

Thank you for your answer.
I'll try step by step over the weekend with your file and try to reproduce it with Big Buck Bunny.
The files I have are all TV episodes with cut out commercials (copyrighted material), so I'm going to transcode BBB to 25fps, demux the file cut the video and audio and remux it.
I think I then have a non copyrighted postable file with the same structure as the others.
I don't know how Kodi tries to keep audio and video in sync. I guess with 15.2 DVDPlayer "slides" the audio and now with 17.0 VideoPlayer drops frames.
Has this method changed in the actual builds? I thought CDVDPlayer/CVideoPlayer was just a name change?
I have no clue why Kodi on Android plays the files without glitches ... I'll investigate that issue further and keep you updated.

Android works by luck, it takes another codepath, especially in combination with passthrough it's just hacked together as one cannot trust neither the audio delay nor the video display.
Besides that, we are currently investigating a solution and on my system it fixed the issue: http://sprunge.us/BZJd it is discussed here: https://github.com/xbmc/xbmc/pull/10284

Thank you! That sounds promising! I'll try these patches. LibreElec building already in progress ...
Time to watch "The Strain" on amazon the next hours
